The Twin Bren is a light machine gun of Chinese origin. The weapon is a double barrel variant of the Bren light machine gun made during the 1950s from ZB26 light machine guns[1]. It came with side by side barrels and was chambered in the 7.62x39mm round fed from AK-47 magazines. The only known example can be seen at the Tongzhou militia museum[2][3][4].
